Inherits from
- ANumericContext: enthought.numerical_modeling.numeric_context.a_numeric_context.ANumericContext
Attributes
- context
Context being derived from:
context = Instance(ANumericContext)
- context_all_names
List of available data item names in the entire context:
context_all_names = Property
- context_base
Base context reference:
context_base = Property
- context_delegate
The ContextDelegate the context uses to handle various policy decisions:
context_delegate = Property
- context_group
The 'name' of the current context group (may be a tuple representing the shape of the group's contents:
context_group = Property(transient = True)
- context_indices
The array indices:
context_indices = Property
- context_items
List of array descriptor items:
context_items = Property(transient = True)
- context_name
The name of the context:
context_name = Property(transient = True)
- context_names
List of available data item names in the current group:
context_names = Property
- defer_events
Whether to buffer 'dict_modified' and 'context_modified' events. When true, no events are fired, and when reverted to false, one pair of event fires that represents the net change since 'defer_events' was set.
defer_events = Property(depends_on = 'context_base.defer_events')
- sub_context_names
The list of all sub_context names:
sub_context_names = Property

Methods
- __contains__(self, *a, **kw)
- __delitem__(self, name)
- __getitem__(self, name)
- __init__(self, context = None, **traits)
Initializes the object.
- __iter__(self, *a, **kw)
- __setitem__(self, name, value)
- __setstate__(self, state)
- bind_dynamic(self, value, trait_name)
Create a dynamic binding to the trait named 'trait_name' on 'value'.
Dynamic bindings maintain the invariant
self[ getattr( value, trait_name ) ] == value
when either 'getattr( value, trait_name )' is changed or when 'value' is renamed within 'self.context_data'. An odd consequence of this is that a dynamically bound value can't be stored under multiple names simultaneously.
Assumes the 'value' and 'getattr( value, trait_name )' domains are disjoint and hashable. (A convenient and probably acceptable restriction.)
See the unit tests for more details.
NOTE: A context with dynamic bindings is (arguably) no longer a dictionary because it might violate substitutability. Consider:
d['a'] = x d['b'] = x assert 'a' in d and 'b' in d
Although we have no set of "mapping object axioms" specifying minimal behavior, I think most users would expect the above assert to always hold for mapping objects, but it can fail if 'd' is a numeric context with a dynamic binding for 'x'.
